Border Beam

Border Beam animates a colored glow around the border of whatever it wraps: install the border-beam package, import the component, and put your own card, button, or input inside it. The playground on the page tunes the beam live, switching the family between rotate and pulse, the shape between a thick beam and a thin line, and the color between the full rainbow and a single hue, with sliders for duration, corner radius, brightness, and hue shift. The same repo ships React, React Native, and SwiftUI ports, and a Copy Prompt button hands the whole setup to an agent.
